SNMP configuration for Nagios: sysUpTime.

[Kevin Keane]

No. These two files are related to the SNMP daemon and the SNMP trap
handling, respectively.

Basically, SNMP has two different ways it operates. You can query client
machines using SNMP, or the client machines can actively send you
information (usually only when some event occurs). Actively sending
information is called a trap. While you can probably make it work with
Nagios, that would be somewhat unusual, and is not what you are looking
for here. The snmptrapd.conf file deals with traps.

check_snmp (and snmpwalk, snmpget etc.) use a plain client/server
approach. On the nagios machine, you have a client - check_snmp. On the
monitored client, you have an SNMP "server" called snmpd (in Linux).
Windows, as well as many routers, switches etc. all also have similar
SNMP servers running.

As the name suggests, snmpd.conf is used to configure this daemon. In
other words, you would need to set that up on the monitored client if it
is a Linux client. check_snmp and snmpget don't use it.

Off the top of my head, I don't know how to configure snmp (probably a
file called snmp.conf - without the d, along with a whole directory tree
under /etc/snmp), but in most Linux distributions it should be pretty
much already configured the way you need it. You may need to install a
couple MIBs for devices you want to monitor.

Most of what you would need to do is done on the command line to the
check_snmp command.
